Hybrid tea rose plant named &#39; RUIY5451&#39;

ABSTRACT

A new and distinct hybrid tea rose plant having attractive large flowers.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a new and distinct variety ofrose plant of the hybrid tea rose class, which was created by crossingan undistributed, unpatented seedling as seed parent with the varietyknown as ‘PANNARAN’ as pollen parent. The varietal denomination of thisnew rose is named ‘RUIY5451’.

SUMMARY OF THE INVENTION

[0002] Among the novel characteristics possessed by this new varietywhich distinguishes it from its parent and all other varieties of whichI am aware are its flower color.

[0003] Asexual reproduction by propagation by grafting and by vegetativecuttings of the new variety as performed in De Kwakel, The Netherlandsshows that the foregoing and other distinguishing characteristics cometrue to form and are established and transmitted through succeedingpropagation.

COMPARISON WITH PARENT

[0004] The new variety differs from its parents in flower color,inasmuch as the flowers of ‘RUIY5451’ are orange red and flowers of theseed parent are cream and light pink and flowers of the pollen parentare salmon.

BRIEF DESCRIPTION OF THE ILLUSTRATION

[0005] The accompanying illustration shows a typical specimen of the newvariety depicted in color as nearly true as is reasonably possible tomake the same in color illustrations of this character.

[0006] In the illustration, 1, 2, 3 and 4 show the foliage; 5 shows astem portion; 6, 7, 8 and 9 show a bud and blooms at different stages ofdevelopment; and 10, 11 and 12 show the reproductive organs.

DESCRIPTION OF THE NEW VARIETY

[0007] The following is a detailed description of the new variety withcolor terminology in accordance with The Royal Horticultural SocietyColour Chart (RHSCC). The terminology used in color description hereinrefers to plate numbers in the aforementioned color chart. Phenotypicexpression may vary with light availability, environmental and culturalconditions.
